Abstract
Abstract A reluctance force brake device applies the coupling and combining concept of the reluctance braking unit to the original rotating source or say mechanical rotation axle for kinetic energy output. The reluctance braking unit, utilizing electrical energy from forward electrical energy source or brake reverse recover energy, generates the reverse reluctance force to reduce the speed of rotating source to operate brake action. The driving design can be extended to absorb the brake reverse recovery energy for recycling in motives related applications, which can help to upgrade or replace the bake system of traditional mechanical vehicles or electrical vehicles, and improve the applicability for drive-by-wire development trend.
